Application filed July 29,

To all 2072 0222 it may concern.

Be it known that I, GEORGE C. L. TISCH, a citizen of the United States,and a resident of Elizabeth, in the county of Union ant State of NewJersey, have invented a new and useful Combination Plate and ThreadGuide, of which the following is a full, clear, and exact description.

This invention relates to attachments for the thread bar of a knittingmachine of the type shownin Patent No. 457,265, issued August 4, 1891,to Julius Frelloehr and Louis Tisch and has for an object to provide animproved construction in the nature of a thread guide wherein the tubemay be ap plied and removed quickly.

Another object of the invention is to provide a thread guide designed tocarry one or more tubes and be held in place by a single clampingmember.

A further object of the invention is to provide an improved plate andthread guide wherein the plate is formed of lugs for assisting inholding a tube in place when clamped to the plate.

In the accompanying drawing:

Figure 1 is a view showing a thread bar associated with a jacquard wheeland a plate and thread guide embodying the invention.

Figure 2 is a front view of the plate and guide member shown in Figure1.

Figure 3 is a sectional view through Figure 2 on line 33.

Figure 4 is an edge view of the structure shown in Figure 2 except oneof the tubes is shown as a left.

Figure 5 is a perspective view of a support and a pair of tubesembodying certain features of the invention.

Figure 6 is aperspective View of a second form of support and tube.

Referring to the accompanying drawing by numerals, 1 indicates what maybe termed a jacquard wheel carrying the usual pins 2 for actuating thethread bars 3. The thread bars 3 are the usual construction used incertain forms of knitting machines (see Patent No. 457,265) and designedto carry a number of plates 4. Each of these plates 4 is provided with anotch or slot 5 for accommodating the clamping screw 6 as shown inFigure 2. The plate 4 is intended for use with tube supports andheretofore the tubes have been arranged with a separate stein for eachtube and a separate clamping Specification of Letters Patent.

member for each tube. In the present invention the plate 4 is madesomewhat diiferent, namely with a pair of bosses or extending lugs 7 anda flange 8 provided with a pair of notches 9 in which the U-shaped tubesupporting members 10 and 11 fit as well as a threaded aperture 7. Thesesupporting members have connected therewith tubes or thread guidingmeans 12 which may be of any size and also may be on either side of themembers 10 and 11. As shown in Figure 6 the member 11 forms a completeU-shaped structure, but the short leg of the hook is of suiiicientlength to fit into one of the notches 9 while the curved end fits overone of the lugs 7. This positively locks the supporting member in placewhen the clamping screw 13 is tightened; this screw being provided witha head overlapping the legs of the U-shaped member 10. A clamping screw14 similar to the clamping screw 13 is provided for the member 10 sothat there is only arranged two screws for two supporting members, andas shown in Figure 2 three tubes are supported by the two supportingmembers, but if desired only two tubes may be supported or four tubes,also the tubes may be made large or small as shown in Figures 5 and 6,and as indicated in Figure 4 the tubes could be on opposite sides ofeither of the supporting members, and in fact the arrangement of thetubes in respect to the supporting members may be right and leftthroughout the entire series. As shown in Figure 5 there are two rightswhile in Figure 6 there is one right. If desired the structure in Figure5 could be two lefts or one right and one left, while the structureshown in Figure 6 could be a left instead of a right as indicated. Thetubes 12 are preferably arranged or positioned so that theirlongitudinal axes will be parallel to the longitudinal axis of the legsof the supporting member 10. As shown in Figure 2, each of thesupporting members 10 fit over a lug 7 and into suitable notches 9 inflange 8 so that when the clamping screws 13 and 14 are tightened, thesupporting member will be rigidly held in place. In applying or removingthe thread guide it is merely necessary to remove the screws 13 and 14and bodily disconnect the guides. The various guides are replaced by areverse action.

In using the attachment the tubes 12 guide the threads from the spoolsto the needles in a well known manner as illustrated in the heretoforementioned patent.

hat I claim is:

1. In a thread guide, a plate provided with threaded openings, spacedlugs above the openings, anda transverse flange below the opening andformed with pairs of notches, each pair of notches being so positionedthat the central axis therebetween willlbe in line with a lug andopening of the plate, and tube-supporting members each having a U-shapedend engaging a'lug of the plate with'the legs thereof seated in a pairof the notches of the flange.

2. Ina thread guide, a plate provided with a transverse notched flange,athreaded opening above the flange and a lug above the opening, athreaded guide supporting member seated in the notched flange and havinga U-shaped end engaging the lug, and a screw screwing into the threadedopening of the plate and engaging the supporting member.

3. In a threaded guide, a plate having a transverse flange provided witha plurality of notches, a threaded opening above the flange, and a lugabove the opening, a thread guide supporting member having a U-shapedend, the U-shaped end engaging the lug and the legs thereof seating inthe notches of the flange, and a screw screwinginto the opening of theplate and engaging the legs ofthe supporting member:
